Does Japan have a 4-day work week?

No. Japan does not have a four-day work week.

Why are people talking about a 4-day work week in Japan?

There are two main reasons people have heard about the four-day work week in Japan.

1) Microsoft Japan ran a four-day work week trial called the “Work Life Choice Challenge” in the summer of 2019. The company claims the four-day trial boosted productivity by 40%.

2) In 2021, a proposal was discussed in Japanese parliament to allow workers to choose a four-day work week.

“This law would enable more people to work fewer hours and be less stressed, which would in turn reduce the likelihood of karoshi [death by overwork].”

How many hours per week do people work in Japan?

The average work week in Japan is 30.7 hours.

In ranking countries from the shortest work week to the longest, Japan ranks 120 out of 187 countries tracked by OECD (36th percentile).

  • 119 countries have a shorter work week than Japan
  • 67 countries have a longer work week than Japan


The average work work is calculated by taking the total annual hours worked per year divided by the average number of people in employment per year, divided by 52 weeks. Therefore, the average work week includes hours for full-time, part-time, and self-employed people. It is not the standard work week for full-time employees.
